random tracks,

Suppose we use two Megatron 747 disks as mirrors of one another. However, instead of allowing reads of any block from either disk, we keep the head of the first disk in the inner half of the cylinders, and the head of the second disk in the outer half of the cylinders. Assuming read requests are on random tracks, and we never have to write:

a) What is the average rate at which this system can read blocks?

b) How does this rate compare with the average rate for mirrored Megatron 747 disks with no restriction?

c) What disadvantages do you foresee for this system?
